Add new callback operations for a dpll device:
- phase_offset_monitor_get(..) - to obtain current state of phase offset
monitor feature from dpll device,
- phase_offset_monitor_set(..) - to allow feature configuration.
Obtain the feature state value using the get callback and provide it to

dp83tg720: Reduce link recovery
This patch series improves the link recovery behavior of the TI
DP83TG720 PHY driver.
Previously, we introduced randomized reset delay logic to avoid reset
collisions in multi-PHY setups. While this approach was functional, it
had notable drawbacks: unpredictable behavior, longer and more variable
link recovery times, and overall higher complexity in link handling.
With this new approach, we replace the randomized delay with
deterministic, role-specific delays in the PHY reset logic. This enables
us to:
- Remove the redundant empirical 600 ms delay in read_status()
- Drop the random polling interval logic
- Introduce a clean, adaptive polling strategy with consistent
behavior and improved responsiveness
As a result, the PHY is now able to recover link reliably in under
1000_ms

Now that the PHY reset logic includes a role-specific asymmetric delay
to avoid synchronized reset deadlocks, the previously used randomized
polling intervals are no longer necessary.
This patch removes the get_random_u32_below()-based logic and introduces
an adaptive polling strategy:
- Fast polling for a short time after link-down
- Slow polling if the link remains down
- Slower polling when the link is up
This balances CPU usage and responsiveness while avoiding reset
collisions. Additionally, the driver still relies on polling for
all link state changes, as interrupt support is not implemented,
and link-up events are not reliably signaled by the PHY.
The polling parameters are now documented in the updated top-of-file
comment.

Add a .soft_reset callback for the DP83TG720 PHY that issues a hardware
reset followed by an asymmetric post-reset delay. The delay differs
based on the PHY's master/slave role to avoid synchronized reset
deadlocks, which are known to occur when both link partners use
identical reset intervals.
The delay includes:
- a fixed 1ms wait to satisfy MDC access timing per datasheet, and
- an empirically chosen extra delay (97ms for master, 149ms for slave).

net: ethtool: add dedicated RXFH driver callbacks
Andrew asked me to plumb the RXFH header fields configuration

is uncertain within netlink. Separate the two for clarity both

This series adds the new callbacks and converts the initial

Add dedicated driver callbacks. Create struct ethtool_rxfh_fields
which contains only data relevant to RXFH. Maintain the names of

For now support both callbacks, once all drivers are converted

Fix ntuple rules targeting default RSS
This series addresses a regression in ethtool flow steering where rules
targeting the default RSS context (context 0) were incorrectly rejected.
The default RSS context always exists but is not stored in the rss_ctx
xarray like additional contexts. The current validation logic was
checking for the existence of context 0 in this array, causing valid
flow steering rules to be rejected.
This prevented configurations such as:
- High priority rules directing specific traffic to the default context
- Low priority catch-all rules directing remaining traffic to additional
contexts
Patch 1 fixes the validation logic to skip the existence check for
context 0.
Patch 2 adds a selftest that verifies this behavior.

Add test_rss_default_context_rule() to verify that ntuple rules can
correctly direct traffic to the default RSS context (context 0).
The test creates two ntuple rules with explicit location priorities:
- A high-priority rule (loc 0) directing specific port traffic to
context 0.
- A low-priority rule (loc 1) directing all other TCP traffic to context
1.
This validates that:
1. Rules targeting the default context function properly.
2. Traffic steering works as expected when mixing default and
additional RSS contexts.
The test was written by AI, and reviewed by humans.

Context 0 (default context) always exists, there is no need to check
whether it exists or not when adding a flow steering rule.
The existing check fails when creating a flow steering rule for context
0 as it is not stored in the rss_ctx xarray.
For example:
$ ethtool --config-ntuple eth2 flow-type tcp4 dst-ip 194.237.147.23 dst-port 19983 context 0 loc 618
rmgr: Cannot insert RX class rule: Invalid argument
Cannot insert classification rule
An example usecase for this could be:
- A high-priority rule (loc 0) directing specific port traffic to
context 0.
- A low-priority rule (loc 1) directing all other TCP traffic to context
1.
This is a user-visible regression that was caught in our testing
environment, it was not reported by a user yet.
